Never say never!
After saying I would not do more changes to the Photo Rig after my Galapagos Trip I felt I needed to.
So this is the photo rig that I will be taking to the Red Sea for a workshop with Alex Mustard.
I got bored with the STIX floats giving away moisture in the luggage and creating issues to other metal parts so decided to completely eliminate the ULCS arms and replace them with Inon float arms size M (they are a tad shorter than the ULCS 8″).
So the arms segments are now 1 Inon Mega S segment and 1 Inon Float M segment connected by a clamp for float arms (2″ effective length). This makes for a fairly long arm that extends to 19.5″ each side from the tray.
This rig is 481 negative in fresh water (with one close up lens) and weights 5.7 Kg so should be around 324 grams negative in salt water and with the fisheye off (Inon UWL-100 28AD with dome) will gently go up. The leak sentinel is
not on the photo but will be also there. The strobe sleeves give quite a lift in shallow water but being neoprene will compress at depth.
The Sola 1200 (used as dive and spotting light not as focus light) is now attached through an M10 ball adapter and clamp so that is mounted exactly in the middle of the port.
I have also changed the diffusers to the AUTO version to use the Inon external auto function, useful to avoid flat shadows.
You will notice the metal ring on the exposure meter of the strobe.
As usual I have bayonet mount 28AD version to be specific, I re-used my old UCL-165AD using an adapter. The float arms host two lens holders.
